SECTION 1- OPERATION
1-1INTRODUCTION
The ETERNALIGHT UPS (uninterruptible power system) from DSPM provides an
exceptional level of load protection and monitoring capabilities. The critical load is
provided with conditioned, regulated, computer- grade power at all times. Both the
voltage level and frequency are controlled at all times to the load.
When the input power is lost to the UPS, such as during a power outage, the UPS
automatically draws power from its internal battery supply. The critical load receives
only clean sine wave power at all times. There are no disturbances or power
interruptions on the output when the UPS transfers to battery operation. Transfers to
and from battery operations are “No Break” transfers. The internal maintenance-free
batteries provide a few minutes to hours (depending upon model) of backup power.
Upon restoration of input power, the UPS automatically resumes normal operation. Also
the UPS immediately begins to recharge the batteries.
The ETERNALIGHT 1 is a dual conversion single phase UPS available in output ratings
of 2 to 80 kVA. The UPS is U.L. listed under UL1778 and/or UL924. The UPS is
available with input voltages of 120, 208, 240 and 277 VAC; and output voltages of 277,
240, 208, and 120 VAC. This information is provided on the nameplate located on the
inside of the front door.

1-2 BENEFITS
The ETERNALIGHT 1 is designed to fit the needs for virtually all power conditioning and
UPS applications. It has been specifically designed to power all forms of modern data
processing, communications, process control equipment, lighting and emergency
lighting equipment. The UPS does not require any derating as other UPS products may
when powering 100% electronic loads including switch-mode power supplies.
The ETERNALIGHT 1 protects sensitive electrical equipment, such as computer
systems, telecommunication networks, LANs, multi-user systems and instrumentation
systems from electrical interference. The UPS protects these systems from power
problems associated with poor quality AC power including complete power outages.
Electrical disturbances can come from practically anywhere: from the incoming power
lines and from within a building. Outside electrical disturbances include lightning strikes,
utility switching, brownouts, and accidents. Electrical disturbances from within the
building can be caused by load cycling (elevators, HVAC systems) fault conditions,
welders, and other electrically noisy equipment. Whether the electrical disturbances are
generated outside or from within the facility, the following power problems will occur:
• Complete power outages
• Brown-outs including momentary sags
• Voltage surges
• Transients including common-mode and transverse-
mode noise
• Frequency shifts and fluctuations
Sensitive electrical equipment needs protection from power problems. Without power
protection, users of sensitive equipment may experience:
• Loss of data including data corruption
• Database corruption
• Equipment and component deterioration
• Premature equipment failures
• Unexpected equipment failures
• Missed deadlines, especially during batch processing
• Loss of real-time transaction processing
• Loss of employee productivity

1-3 PRODUCT FEATURES
The following describes the major sub-systems within the ETERNALIGHT 1 UPS.
INPUT AND OUTPUT FILTER – The input filter reduces the input transients and
harmonics on the input line. This helps protect the electronic circuitry of the UPS. The
output filter filters and noise and line spikes from loads.
INPUT POWER FACTOR CORRECTION - The ETERNALIGHT 1 UPS system includes
state – of – the – art input power factor correction. This greatly reduces the amount of
current demanded from your building wiring system, yielding a highly efficient “Building
Friendly” UPS System.
RECTIFIER/INVERTER
The Rectifier-Inverter system provides controlled sine wave power to the output. The
output voltage and frequency are monitored by the microprocessor and controlled to
provide precision power with changing inputs and outputs to the UPS system.
MICROPROCESSOR, Display
The microprocessor monitors the input and the output to the UPS system and corrects
for any abnormal condition that may occur. This is displayed on the display for operator
information.
DIAGNOSTIC TESTS
When you start the UPS, a diagnostic test is automatically executed that checks the
electronics, batteries, and reports and problems on the display.

SECTION 2 – PREINSTALLATION
2-1 SITE PLANNING AND PREPARARTION
The ETERNALIGHT 1 is designed for installation indoors where it is protected from the
elements. The UPS can be installed in a variety of different environments including
computer rooms, offices, and industrial/process control locations. For the best
performance and reliability, temperature extremes should be avoided.
Listed below are the environmental specifications for the ETERNALIGHT 1 UPS
SYSTEM.
Adequate clearance around the equipment should be provided for service access and
proper equipment cooling. The UPS must be protected from contact with water and
other liquids. If the UPS is installed in a small, enclosed area, provisions for additional
cooling may be necessary.
OPERATING ENVIRONMENT. Provide an operating environment that meets the
following conditions:
o AMBIENT TEMPERATURE 32°to 104°F
0°to 40°C
o OPERATING ALTITUDE 2,286 M (7500 FT)
o NON-OPERATING ALTITUDE up to 3,048 M (10,000 FT)
o RELATIVE HUMIDITY 0% to 95% (non-condensing)
Operating the UPS and batteries at either extreme of the temperature range may affect
the long-term reliability of the system. This is especially true of the sealed,
maintenance-free batteries. Sealed, maintenance-free batteries are designed to operate
at normal room temperatures (72 to 77°F)
! WARNING ! BATTERY SHELF LIFE !
• BATTERY SHELF LIFE, WHEN STORED UNDER TEMERATURE CONDITIONS of
66°F ~ 77°F, is FOUR (4) MONTHS MAXIMUM AFTER THE SHIP DATE.
• BATTERY MUST BE RECHARGED FOR EIGHT HOURS AFTER THIS DATE
OTHERWISE THEY MAY BE DAMAGED.
